Turtle R7RS
===========
This library is for turtle graphics implemented in R7RS Scheme. Because there is no portable way to implement graphics, the code was made modular enough to have multiple front-ends. For Gauche, gauche-tk is used. For Kawa, the built-in HTTP server is used to send instructions to a browser front-end.

YASOS is a dependency to allow extending the turtle.
